As many others have said the adhesive is dull and will not stick. A simple solution: buy a small tube of suitable glue that you can apply with a needle. The real problem is quality control. Bought 2 replacement cables based on reviews, one has a DOA power button and the other has a DOA screen lock switch. I chose the lesser evil and stayed without a screen lock.
